Twitter sues the Department of Justice and the FBI in the U.S. District Court for the Northern District of California. The complaint asks the court to hold that Twitter is not bound by a January 2014 letter from the Deputy Attorney General to Google, Yahoo!, Microsoft, LinkedIn, and Facebook (the DAG letter) in response to an action in the Foreign Intelligence Surveillance Court by these companies. Although Twitter wasn’t a party to this action, “the DOJ and FBI told Twitter that the DAG Letter sets forth the limits of permissible transparency-related speech for Twitter,” including reporting on NSLs and told Twitter it couldn’t publish unspecified information in an April 2014 draft transparency report. Twitter’s complaint argues it shouldn’t be bound by a settlement it wasn’t a party to, and asks the court for declaratory judgment that it can publish its April 2014 transparency report. It also asks the court to hold that NSL gag orders and judicial review procedures are unconstitutional.
